MEANS FOR REMOVING FLUFF OR DUST FROM SPINNING-BRANT GUIDES.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed November 18, 1918. Serial No. 262,960.

. T 0 all whom it may concern:

the spindles to guide the rovings passing from the drawing rolls to thespindles. These rovings being-of light, delicate character, depositfluff or dust on the guides which accumulates and is liable to catch onthe rovings and form enlargements thereon,

, of one good form which either will not pass through the guides andtherefore cause the rovings to be broken, or will produce lumps on theyarn, impairing its quality.

A continuous current of airdirected to the guides will clear the fluffor dust therefrom, but a continuous current is liable to break thelight, delicate rovings, and if broken from this or other causes, thecontinuous current of air will blow the loose ends of the rovings about,thereby rendering it difficult to pick up and reconnect the ends of therovlngs, and frequently the loose ends are.

blown over to and unite with rovings passing to adjacent spindles.

The present invention utilizes an air current for removing the fluff anddust from the guides, but the current is applied intermittently in theform of gentle pufi's of air with a frequency suflicient to preventobjectionable accumulation of flufi or dust on the guides, but withintervals of substantial duration between the pufi's when there is noair current 011 the rovings, and therefore, no liability of breakingthesame, and if the rovings should be broken from other cause, theintervals afford the operator suiiicient opportunity to pick up andreconnect the loose ends of the rovings.

The character of the invention will be best understood from thefollowing description of means for carrying the invention into practicaleffect, shown in the accompanying drawing, wherein Figure 1 isaconventional showing of an assembly of members typifying parts of aspinning machine and equipped with one form of means which may beemployed to produce the intermittent puffs of air on the guides; and

Fig. 2 is a plan of the parts shownv in Fig. 1.

eferring to the drawing, 1 designates a spindle typifying one of thespindles of a spinning machine which may be operated by means well knownin the art, and therefore, unnecessary to illustrate herein. 2 and 3typify the usual drawing rolls of a spinning machine mounted on shafts 5and 7 driven in the usual manner. The rovings 9 pass between the drawinrolls to the spindles 1, and are guided in t eir passage therebetween byguides, in the resent instance, in the form of slots nected by hinges 15with an inclined plate 11 (Fig. 2) ma board 13 con- 17 mounted on andsecured to the frame member 19.

The character of the rovings is such that Next will be described onegood form of means for producing the intermittent pufis of air on theguides to remove the flufi' or dust therefrom. This means, in thepresent instance, comprises a bellows 23 having a plate 25 secured tothe frame member 19 and a movable or may be of a length sufficient toproduce the intermittent puffs of air on the guides for hinged plate 27This bellows a'series of spindles of any number as desired,

i and the bellows may be provided with an air discharge mouth 29desirably in the form of a slit extending along and adjacent to theupper surface of the frame member 19.

Any suitable means may be provided for operating the bellows. In thepresent instance, this means comprises an arm 31 secured to the hingedplate 27 adjacent the free edge thereof and adapted to be engaged atintervals by a roller 33 on an arm 35 fast on a shaft 37 journaled inhearings in the frame. This shaft may be provided with any appropriatedriving means to continuously rotate the same. In the present instance,the shaft has a pulley 39 fast thereon connected by a belt 41 with asimilarpulley 43 on a countershaft.

In operation, the roller 33 once in each r0- tation of the shaft 37 willengage 'the arm 31 and thereby rock the hinged plate 27 of the bellowsupward to expand the latter and fill the same with air. After the rollerhas lifted the bellows arm as described, it will pass beyond said armand thereupon the bellows will be gradually collapsed by the weight ofthe hinged plate 27. This will produce a gentle puff of air in the formof a stream passing from the mouth of the bellows and directed thencealong the top of the guide member 19 and the inclined plate 17 to theboard-13. In passing over the latter, it will blow the flufi or dust onthe guide board adjacent the slots 11 and remove the same therefrom.While the bellows is collapsing, the roller 33 will slowlycumulate insubstantial amount on the guides, merely a gentle current of air willsuflice to remove the same therefrom, and

i the force of the current will not be sufficient to break rovings ofnormal character. If,

however, the rovings should be locally at tenuated or weakened to suchan extent that the air current will break the same, or if the rovingsbecome broken from other cause, the intervals between the puffs of airare suflicient to enable the operative to readily pick up and connectthe ends of the rovings. The broken ends of the rovings will not beblown about and render it diflicult for the operator to pick up thesame, and there will be no danger of blowing the loose ends of therovings over to unite with adjacent rovings.

By the invention simple and effective means is provided for removing theflufl' or dust from the guides, and while this means,

in the present instance, is in the form of a bellows, it will beunderstood that other means may beemployed for producing theintermittent puffs of air as described.

Having described one good form of the invention without limiting thesame thereto, what I claim as new and desire to secure by Letters Patentis 1. In a spinning machine, the combination of drawing rolls, aspindle, a guide for a roving between said rolls and spindle, and meansto produce intermittent puffs of air to remove fluff or dust from saidguide.

2. Ina spinning machine, the combination of drawing rolls, a spindle,means to guide a roving in its transit from the rolls to the spindle, abellows to produce intermittent puffs of air to remove fluff or dustfrom said guide, and means automatically to operate said bellows.

3. Ina spinning machine, the combination of drawing rolls, a spindle, aguide for a roving between the drawing rolls and spindle, means toproduce intermittent puffs of air, andmeans to direct the air to saidguide to prevent accumulation of fluff or dust thereon such as mightbreak the roving or impair the spun yarn.

4. In a spinning machine, the combination of drawing rolls, a spindle, aguide for a roving between said rolls and spindle, and means to produceintermittent pufl's of air on the guide to remove flufl or dusttherefrom and comprising a bellows, a rotary member, and means actuatedby said rotary member for operating said bellows.

5. In a spinning machine, the combination of a series of drawing rolls,a series of spindles, a series of guides for rovings between said rollsand spindles, and a bellows common to said guides for producingoccasional pufis of air to remove flufi' or dust from said guides. K 6.In a machine of the character described, the combination of a guide fora roving, air receiving means having a mouth directed toward said guide,and means for automatically causing intermittent pufls of air to passfrom said mouth to said guide to remove fluff or dust therefrom.

7. In a machine of the character described, the combination of a memberhaving guide openings for rovings therein, air receiving means having adischarge mouth of suflicient length to deliver a current of air to saidguide openings, and means for causing the air to pass from said mouth inthe form of intermittent pufi's to remove fluff or dust from portions ofsaid member adjacent said guide openings.

In testimony whereof I have signed my name to this specification.
